John Deere Diesel engines – Lots of power

Whether as 3-, 4- or as a 6 cylinder with displacements of 2.4, 3.0, 4.5, 6.8, 9.0 or 13.5 liters, all John Deere PowerTech engines have a high torque increase and lots of power being at the same time very cost efficient.

John Deere Engines fulfill tomorrow's demands – TODAY!

You can find PowerTech engines as the driving force in all important genuine John Deere products, in tractors, combines, harvesters and telescope loaders. In the meantime numerous other OEMs have also recognized the advantages of John Deere engines and lots of PowerTech engines are running in their special vehicles, construction machinery, gensets, compressors, boats.

Gas engines – Clean and Powerful

Together with our partners in the US we offer a complete line of gas engines from 3.0 liter to 10.3 liter displacement based on various American automotive engines. Outstanding durability and comprehensive application possibilities come with these engines.More about Gas engines

We offer a complete line of gas engines up to 10.3l displacement based on American automotive engines. They are available for industrial use, as gensets or in a premium version, prepared for the demanding application in co-gen units.

The following types are available:1.6l 4-cylinder inline engine (14 to 43 kW)OHC gasoline engine with 4 cylinders and overhead camshaft, originally developed for small cars. The camshaft is belt driven with a maintenance-free valve clearance adjustment by hydraulic tappets.

The 1.6l engine is available as industrial or genset unit and can be operated with natural gas (NG) or liquid gas (LPG). For industrial applications a gasoline version is also available.

3.0L 4-Cylinder Inline Engine (20 to 54 kW)

The 3.0l OHV engine has also 4 cylinders, but a gear driven side camshaft. Valves are actuated maintenance-free by hydro lifters together with push rods.

It is available as industrial, genset or co-gen engine and can be operated with natural gas (NG) or liquid gas (LPG). For industrial applications a gasoline version is also available. Co-gen version comes with premium cylinder head with hardened valve seats and electronic engine control with a close loop for extended life time. In addition, it has a water-cooled exhaust manifault to optimize thermal efficiency.

4.3 Liter, 6-Cylinder V-Engine (30 to 108 kW)

The 4.3l OHV engine has 6 vee-type cylinders and a bottom-mounted gear driven camshaft. Valves are actuated maintenance-free by hydro lifters together with push rods.

It is available as industrial, genset or co-gen engine and can be operated with natural gas (NG) or liquid gas (LPG). For industrial applications a gasoline version is also available.

5.7 Liter, 8-Cylinder V-Engine (42 to 125 kW)

The 5.7l OHV engine has 6 vee-type cylinders and a bottom-mounted gear driven camshaft. Valves are actuated maintenance-free by hydro lifters together with push rods.

It is available as industrial, genset or co-gen engine and can be operated with natural gas (NG) or liquid gas (LPG). The co-gen version has a premium-cylinder head with hardened valve seats and an electronic engine control with a close loop for extended life time.

8.0 Liter 8-Cylinder V-Engine (67 to 186 kW)

The 8.0l OHV engine is basically identical to 5.7l engine. It also has 8 vee-type cylinders and a bottom-mounted gear-driven camshaft. Valves are actuated maintenance-free by hydro lifters together with push rods.

It is available as industrial, genset or co-gen engine and can be operated with natural gas (NG) or liquid gas (LPG). The co-gen version has a premium-cylinder head with hardened valve seats and an electronic engine control with a close loop for extended life time. In addition, it has a water-cooled exhaust manifault to optimize thermal efficiency. Most of the auxiliary equipment of the well-known GM V8 engines can be used.

The basic concept of our 10.3l OHV engine is similar to the 5.7l engine with 8 vee-type cylinders and bottom-mounted gear-driven camshaft. Valves are actuated maintenance-free by hydro lifters together with push rods.

It is available as industrial, genset or co-gen engine and can be operated with natural gas (NG) or liquid gas (LPG). The co-gen version has a premium-cylinder head with hardened valve seats and an electronic engine control with a close loop for extended life time.

The proven John Deere PowerTech engines have been redesigned.Today the PowerTech E®, PowerTech M® and PowerTech Plus® fulfill the emission regulations of STAGE 3A / TIER 3 and comply with Stage 3B / Interim TIER 4 standards, by the way without using SCR (Selective Catalytic Reduction) – by urea injection.At INTERMAT 2012 John Deere Power Systems introduced the new engines Final Tier 4 / Stage IV.

To meet increasingly stringent emissions regulations, John Deere has followed a carefully planned approach. Deere have systematically adopted new technologies like cooled exhaust recirculation (EGR ), exhaust filters or selective catalytic reduction (SCR) and integrated them with field-proven solutions to meet each regulatory tier.

The John Deere Integrated Emissions Control system for Final Tier 4/Stage IV is optimized to meet emissions regulations while delivering improved performance, uptime, and efficiency. Uncountable hours in test cells, in prototypes as well as under the hardest condition of all – in real off highway application at work – proved the usability and showed the ability to satisfy or outperform customer’s highest expectations.

With John Deere you’ll get optimized solutions for consumption and efficiency. The specific SCR-sytem, higher injection pressures and less use of DEF fluids result in a total fluid consumption you might have experienced with our IT4/Stage IIIB engines or even better.

If your engine manufacturer isn’t talking about diesel exhaust fluid (DEF) consumption, they may not be telling you the total efficiency story. John Deere Final Tier 4/Stage IV engines not only reduce diesel fuel consumption, but they demonstrate exceptionally low DEF consumption as well.

John Deere Final Tier 4/Stage IV engines operate efficiently with ultra-low sulfur diesel as well as B5 to B20 blends, providing optimal performance and fuel-choice flexibility.

Once again John Deere is setting a benchmark for power, usability and comfort.

John Deere Engines enable you to offer a unique combination of power, environmental compatibility and fuel efficiency in your machines.
